  • Deformable Silver Coated PMMA Microsphere Spacers

    Silver Coated Glass Microspheres work well for increasing the conductivity of bond lines, but they lack the capability to deform when compressed to give increased conductive contact between the surfaces of the bond line.  These newly released Silver Coated PMMA Microspheres offer the low weight deformable pmma cores, and 250nm thick silver coating for high conductivity.

    Conductivity of this product has been measured at <0.5ohm per square with a 30% by volume preparation.  Sizes available cover both the common 50 micron (45-53um)  and 100 micron (90-106um) sizes and many others.

    These spheres are perfect for producing anisotropic (only conductive in one direction) conductive bond lines.

    Actual bond line thickness achieved will be a function of the assembly pressure and the size spheres selected.

    In addition to being high conductive these silver coated PMMA is bio-compatible.
